Chelsea's recent form
The Blues are seeking to win three successive Champions League games for the first time since November/December 2015 and are hoping to avoid two consecutive home defeats in Europe for the first time.We are without a win in our past four Champions League matches at the Bridge (three draws, one defeat. We have never gone five home games without a victory in the competition.Michy Batshuayi has scored one goal every 47 minutes for the Blues in the Champions League (three goals in 141 minutes) – the best minutes per goal ratio of any Chelsea player in the competition.
Frank Lampard has handed five Englishmen aged 21 or younger their Champions League debuts for Chelsea this season (Mount, Abraham, Tomori, James, Hudson-Odoi) – the most by a team in a single season in the competition’s history.Chelsea have lost just one of our last 18 games in Europe (14 wins, three draws) in a run that includes winning the Europa League last season; our only defeat was on matchday one of this Champions League campaign at home to Valencia.Lampard could become the first English manager to win three of his first four matches in the Champions League, with Bobby Robson and Harry Redknapp winning two of their first four.

Ajax lost two of their 18 European matches in 2018/19 (10 wins, six draws), when they became the first side in European Cup history to reach the semi-finals having come through three qualifying rounds and the first Dutch club to get to the Champions League last four since PSV Eindhoven in 2004/05.Ajax are seeking a sixth successive away win in the Champions League (excluding qualifiers). Their current five game winning run were at AEK Athens (2-0), Real Madrid (4-1), Juventus (2-1), Tottenham (1-0) and Valencia (3-0).Ajax have never lost an away Champions League match in England (one win, three draws), winning most recently away at Tottenham in April 2019. Their last away European Cup defeat on English soil was in April 1980, a 2-0 semi-final defeat against Brian Clough’s Nottingham Forest side.
